5-Aminolevulinic Acid and 24-Epibrassinolide Improve the Drought Stress Resilience and Productivity of Banana Plants.

Plant growth, development, and productivity are adversely affected under drought conditions. Previous findings indicated that 5-aminolevulinic acid (ALA) and 24-epibrassinolide (EBL) play an important role in the plant response to adverse environmental conditions. This study demonstrated the role of ALA and EBL on oxidative stress and photosynthetic capacity of drought-stressed 'Williams' banana grown under the Egyptian semi-arid conditions.

The Mechanism of Citrus Host Defense Response Repression at Early Stages of Infection by Feeding of Transmitting Liberibacter asiaticus.

Citrus Huanglongbing (HLB) is the most devastating disease of citrus, presumably caused by " Liberibacter asiaticus" (Las). Although transcriptomic profiling of HLB-affected citrus plants has been studied extensively, the initial steps in pathogenesis have not been fully understood. In this study, RNA sequencing (RNA-seq) was used to compare very early transcriptional changes in the response of Valencia sweet orange (VAL) to Las after being fed by the vector, (Asian citrus psyllid, or ACP).
